Tests

This patch was testing by creating a local wheel package add installing it using docker test-envs for Centos7.

FROM centos:7

RUN yum install -y python3-devel python3-pip gcc

ENV PATH="/root/.local/bin:${PATH}"

RUN pip3 install --user --upgrade pip setuptools wheel

WORKDIR /test

Added a tab in docs/getting-started/troubleshooting for rhel7 install fix.

Awesome! I just published the package.

pip install fiftyone-db-rhel7

To make this PR complete, can you just add the build and upload steps for rhel to our build-db workflow?

Essentially, just add this ad the [debian9 build wheel step]( debian9 step#L64):

      - name: Build wheel (RHEL/CentOS 7 x86_64)
        env:
          FIFTYONE_DB_BUILD_LINUX_DISTRO: rhel7
        run: |
          cd package/db
          python setup.py bdist_wheel --plat-name linux-x86_64

And this after the debia9 upload step:

      - name: Upload wheel (RHEL/CentOS 7)
        uses: actions/upload-artifact@v2
        with:
          name: wheel-rhel7
          path: package/db/dist/*rhel7*.whl

Thanks for your guidance, i added the necessary steps to the build. Hope everything is fine.

I'm also working on a tutorial on Fiftyone with MLFlow integration, hope i can share it soon.
